11. The crusher according to claim 1, wherein one or more of said first and second securing members are separately joined, non-integral portions of said piston rod.
12. The crusher according to claim 1, wherein the piston rod comprises at least one mount for supporting at least one of said first and second securing members.
13. The crusher according to claim 1, wherein at least one of said first securing member, second securing member, and mount comprise one or more of the following: a centering washer, a centering cup, a centering portion, a centering bearing surface, or a centering feature.
14. The crusher according to claim 13, wherein said centering washer, centering cup, centering portion, centering bearing surface, and centering feature comprise a tapered, conical, or spherical surface.
15. A crusher clearing system adapted for providing crushing forces to components of a crusher and clearing forces to components of the crusher to facilitate the removal of tramp material from the crusher, the crusher clearing system comprising:
a dual-acting cylinder having a body and a piston rod movably disposed in relation to said body, the piston rod further comprising a first securing member adjacent a distal portion of the piston rod and a second securing member adjacent a proximal portion of the piston rod, wherein the first and second securing members are configured to capture a mounting portion of an adjustment ring therebetween;
wherein the first securing member is configured to seat against an upper surface of said mounting portion and apply a crushing force to the adjustment ring; and the second securing member is configured to seat against a lower surface of said mounting portion and apply a clearing force to the adjustment ring; and
wherein the body of the cylinder is configured to be securely mounted to a second mounting portion of a second member by a cylinder mount.
16. A method of clearing a crusher including the steps of:
providing a crusher comprising: a first member having a first mounting portion; a second member having a second mounting portion; a dual-acting cylinder having a body and a piston rod movably disposed in relation to said body, the body being securely mounted to the second mounting portion of the second member by a cylinder mount; wherein the piston rod further comprises a first securing member and a second securing member; wherein the first mounting portion of the first member is captured between said first securing member and second securing member to secure the piston rod thereto;
filling a first chamber of the dual-acting cylinder to provide a crushing force between said first member and said second member; and
filling a second chamber of the dual-acting cylinder to provide a clearing force between said first member and said second member.
17. The method of claim 16 further comprising the step of passing a fluid directly from the first chamber to the second chamber via a crossover tube extending between a first crossover port communicating with the first chamber and a second crossover port communicating with the second chamber, in order to prevent mechanical overload of the crusher.
18. The method of claim 16 further comprising the step of passing a fluid through a relief valve separating the first and second chambers, in order to prevent mechanical overload of the crusher.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A valve bridge adjustment tool comprising top and bottom sections disposed in fixed relation to each other, the bottom section further comprising a recess that is releasably engageable with a knuckle of the valve bridge to stabilize the valve bridge during selective loosening or tightening of a jam nut disposed adjacent to a surface of the valve bridge, and the top section further comprising a hexagonal outer wall and a substantially cylindrical bore adapted to receive the jam nut upwardly through the recess into the bottom portion of the bore, the bore providing sufficient clearance around the jam nut to permit insertion of a conventional socket into the top of the bore and into engagement with the jam nut.
2. The valve bridge adjustment tool of claim 1 wherein the recess is U-shaped.
3. The valve bridge adjustment tool of claim 1 wherein the recess has a forwardly facing open end.
